Product Description

Product Description:


White corundum is a product that is made from industrial alumina powder. Its production is a process that requires a very high temperature, greater than 2000 degrees, melted in an arc furnace. Once cooled, grinding and shaping take place, alongside magnetic separation of iron and the selecting of particles of the required size.


The resulting white corundum is distinct for its close texture and high hardness, as well as its angular shape. It is suitable for many applications, such as the manufacture of ceramics and resin consolidation abrasive tools. It can also be used for grinding and polishing, sandblasting, precision casting, and the making of high-grade refractory materials.




Raw manufacturers have a great advantage over outsourced production, which is complete control over the production process. This allows them to accurately monitor the quality of their products, as well as quickly react to any changes or issues in demand. Additionally, these manufacturers can save money over time by avoiding the markup associated with purchasing from third-party suppliers.


Thus, the production of raw materials in-house can be a smart investment and benefit a manufacturer in the long run. Having control over production and cost savings both provide significant advantages that should be taken into consideration.


Technical Parameters:

White corundum is an alumina oxide named Al2O3 with a density of 3.95 g/cm³ and a Mohs hardness of 9.0. It has a tripartite crystal system structure and a compressive strength of 2000 MPa, a tensile strength of 400 MPa, a flexural strength of 480 MPa, a thermal expansion coefficient of 8×10^-6 K^-1, and a thermal conductivity of 29 W/(m-K). Furthermore, it has a great thermal stability and can withstand use in extreme high temperatures.



White corundum abrasive is an ideal choice for dealing with all kinds of high-end products or their surface. It can take care of the rust on the iron workpiece with its decontamination and derustifying properties, as well as increase the adherence of the coating afterward. When it comes to aluminum workpieces, it can remove the oxidation skin as well as strengthen and make the surface glossy. For copper workpieces, it also provides oxidation skin removal to achieve matte effects.
